What Is There To Know About Welding Sheet Metal? Easy Open Ends and peelable ends offer quick and easy removal, helping consumers enjoy their meals without the need for a can opener. The hallmark of Easylift easy-open ends is the significantly improved finger access between the tab and the lid. PeelSeam peelable ends feature a thin, flexible foil heat-sealed to a rigid steel or aluminum ring. By grasping the tab on the lid, consumers can open the package in one simple, fluid gesture, leaving no sharp edges. In addition to being easy to open, both ends offer an unrivaled barrier against light, oxygen and water ingress, all of which are essential for maintaining the flavor and sterility of foods that are consumed without extra preparation. CNC machining is a rapid manufacturing process that turns digital 3D designs into plastic or metal parts by selectively cutting away material. Many companies require CNC machining services to make parts and prototypes, and many industries use versatile technology. But CNC machining comes in various forms. Although all CNC machining technologies follow a similar workflow — software turns the digital design into machine instructions, which instruct the CNC machine to cut material — the hardware for cutting material can differ greatly between machines. This article discusses the main differences between two of those machines: CNC mills and CNC turning (or lathes centers). In the article we discuss the essential features of CNC Machining Milling and Turning while also presenting the main advantages of each technology and a selection of common parts that companies can manufacture using each process. CNC milling is one of the most common CNC machining services, and machinists can use it to make a wide variety of CNC machined parts. Prototype companies often use CNC mills to make one-off functional prototypes. CNC mills use computer instructions to move a rapidly rotating cutting tool along three or more axes. When the spinning cutting tool makes contact with the workpiece, it removes material in a controlled manner. The cutting tool makes a succession of passes against the surface of the workpiece until the workpiece resembles the desired part. Die Casting is a metal casting process that forces molten metal into a mold. It produces dimensionally accurate precision metal parts that have a flawless smooth finish. Its ability to produce detailed parts makes it perfect for the mass production products. Die castings are made from non-ferrous metals such as zinc, copper, aluminum, magnesium, lead, pewter, and tin. The two methods of die casting are hot or cold chambered. The process that is used depends on the type of metal and the part. The cold chambered method is used with metals that have a high melting point such as alloys of aluminum, brass, or copper. Hot chambered die casting is limited to metals that won't dissolve when heated such as zinc, lead, and magnesium alloys. The process of die casting is efficient, economical that offers a broad range of shapes and components. Parts produced have a long life and can be produced to be visually appealing giving designers significant advantages and benefits. The high speed of die casting produces complex shapes with close tolerances requiring no after production processing. There is no need for additional tooling or shaping. Final parts are heat resistant with high tensile strength. It's been evident since the start of 2021 that construction, both commercial and residential, is exponentially expanding in our region – to our industry's, and our economy's, gain. However, this growth in construction has also created an adverse effect on one of the most important aspects that keeps the industry functioning smoothly: the construction supply chain. As construction projects continue to rise, general contractors' needs for Building Materials and supplies have also increased, which has created a surge of demand that's been weighing on the supply chain. Here's a deeper look into this recent trend in our industry, considerations for adaptations to construction processes, and solutions general contractors can implement to diminish the negative effects. The cost of materials According to Associated General Contractors (AGC), government data released earlier this month, another round of costly pricing increases and supply chain disruptions have perpetuated further hardships on contractors in our region, not only driving up construction costs, but also slowing down progress on their projects. In some cases, prices per unit almost doubled. Additionally, the data found that more than three-fourths of construction firms have indicated projects are being postponed or canceled due to unavailable materials or cost overruns, while only one out of five reported winning new work in the previous two months. What is welding? It's a Sheet Metal Welding fabrication technique that joins together two pieces of metal, glass, or thermoplastics with similar melting points and compositions using fusion. When did it first occur? 1800s: More than 2,000 years ago in the Bronze Age, small, gold circular boxes are made by pressure welding lap joints together. During the Iron Age, Egyptians and Eastern Mediterraneans learn to weld iron before the art of blacksmithing is developed during the Middle Ages. During this time, gas, cutting, and resistance welding are developed. Nikolai Benardos and Stanislaus Olszewski secure a British patent in 1885 and an American patent in 1887 for welding. This was the beginning of carbon arc-welding with iron and lead.
